Optical parametric oscillator pumped at ~one µm with intracavity mid-IR big difference-frequency generation in OPGaAs
Output idler energies to the microjoule degree are obtained with most conversion effectiveness of 11% with the amplifier stage, that is more than two situations much better than the outcomes acquired with an analogous sample of your broadly spread product AgGaS 2 .
Besides the compactness and benign running features, it absolutely was the large overall flexibility in design and style and output traits that led into the achievements of reliable-point out lasers over the last forty yrs.
The strategy of chemical transport reactions (volatilization of a fabric via a reduced-volatile chemical intermediate in a temperature T1 and back-response from the combination in a temperature T2, using the temperature dependence with the chemical equilibrium involved) is often a valuable Resource for growing single crystals of many elements which cannot be effortlessly obtained through the soften.
We report new experimental outcomes over the period-matching Houses of yellow colour HgGa2S4 crystals for harmonic era of an Nd:YAG laser-pumped KTiOPO4 (KTP) optical parametric oscillator (OPO) and CO2 lasers in the 0.944-ten.5910 μm array. Moreover, we present new Sellmeier equations that give a very good reproduction with the current experimental results and also the printed information details for second-harmonic technology of CO2 laser radiation at 9.
brought about oscillations during the idler wavelength of fewer than 200MHz over 300s; the short-term stability was fewer than 3MHz
The temperature dependence of refractive indices of optical products is characterized During this get the job done by what we call their normalized thermo-optic coefficients. These are typically determined experimentally by way of interferometric measurements of thermal enlargement and of changes in optical thickness at a couple of laser wavelengths as operate of temperature. An appropriate vectorial formalism placed on these details allows predicting the thermal evolution from the refractive index all over the beneficial choice of transparency.

The technologies of expanding mercury thiogallate crystals (HgGa2S4) is enhanced and superior-excellent bulk samples are developed. The basic optical and thermal Attributes of those crystals are researched. The transmission spectra of mercury thiogallate are measured and its nonlinear features like the quadratic susceptibility, tuning curves, and also the optical-destruction resistance also are determined.
The electronic construction and chemical bonding in HgGa2S4 crystals developed by vapor transportation method are investigated with X-ray photoemission spectroscopy. The valence band of HgGa2S4 is observed to generally be formed by splitted S 3p and Hg 6s states at binding energies BE=three 7 eV and also the factors at BE=7 11 eV created by the hybridization of S 3s and Ga 4s states with a robust contribution within the Hg 5d states. At better binding energies the emission lines related to the Hg 4f, Ga 3p, S 2p, S 2s, Hg 4d, Ga LMM, Ga 3p and S LMM states are analyzed during the photoemission spectrum.

Latest mid-IR NLO crystals is often divided into four groups, i.e., classical binary and ternary metallic pnictides and chalcogenides, quaternary metal chalcogenides, binary and ternary steel halides, and different-bond-variety hybrid compounds that have a minimum of two sorts of obviously diverse check here chemical bonds during the crystal structures. Steel pnictides and chalcogenides have bought A lot consideration on escalating big crystals. Distinct-bond-form hybrid is a new loved ones of mid-IR NLO resources, and a lot of of these were found in the last 10 years. In steel halide technique, both equally development in escalating large crystals and discovering new ones happen to be produced.
Tunable mid-IR radiation is received through 2nd harmonic generation of tunable CO2-laser radiation utilizing a CdGeAs2 crystal. Its angular tuning attributes within the CO2- laser wavelength, angular acceptance angle and spectral acceptance are measured.
